Training on your own? (2000 fide elo)(Titled players pleeeease answer too :D)

So anyways, I'm rated around 2000 in the FIDE rating system, but I can't really afford a personal coach or premium memberships, but I could maybe buy a good book or a program or something, now I just have a Mega Database 2014(Fritz and Chessbase included) so I was wondering how I could improve on my own. Especially considering my time is limited because I'm really into studying right now, need to take care o' my future. I'm a positional player, and my opening repertoire is pretty solid, and I have done quite a lot of tactics training. :)

Now I just need some kind of a plan or a general direction or something, not just "work this book- the end."

Thanks for reading! Looking forward to answers :)
